“These savings come through the increased control I have with the [MVP Conductivity] probe over either test strips or titration kits,” continues Wakefield. “Matching a test strip to a color patch associated with 100, 200, or 400 parts-per-million (ppm) is so subjective, especially from employee to employee. Even titration kits show serious variation and simply aren’t accurate enough. I can measure the solution three different times and easily get three different values for my solution concentration using titration kits.
